Method for controlling an operating parameter of an acoustic apparatus

A method for controlling an operating parameter of an acoustic apparatus, the method comprising:

• implementing a screen displaying at least one window, the at least one window including at least a portion of a cursor able to occupy a plurality of positions relative to a fixed reference of the at least one window, each cursor position (i) representing a current selectable value of an operating parameter, and (ii) defining a respective range of selectable values of the operating parameter, the range of selectable values having an amplitude strictly less than the difference between a maximum value and a minimum value of the operating parameter;
• displaying the cursor in an initial position relative to the fixed reference, alignment of the fixed reference relative to the cursor representing an initial selected value of the operating parameter;
• acquiring an elementary command from an operator, the operator moving a pointer in the at least one window;
• obtaining a speed parameter of the pointer, the speed parameter being representative of a speed of the pointer projected over the direction of movement of the cursor;
• sliding the cursor with respect to the fixed reference, in a direction of movement along the cursor, at a speed equal to the speed parameter of the pointer if the speed parameter of the pointer is above a predetermined threshold, or at a speed lower than the speed parameter of the pointer if the speed parameter of the pointer is less than or equal to the predetermined threshold, from the initial position to a final position in order to select a final selected value of the operating parameter, wherein sliding of the cursor is constrained to prevent the final selected value from being outside of the range of selectable values defined by the initial position of the cursor;
• and
• sending the final selected value of the operating parameter to the acoustic apparatus.
